' IMPROVEMENT IN LIQUID-METERS.

Specification forming part of Letters Patent No. 1 3,633, dated September 24, 1872.

To all 'whom 'it may concern:

Be it known that I, GERARD SIcKELs, of Boston, in the county of.Suii'olk and State of Massachusetts,have invented kcertain Improvements in Water or other Meters, of which the following is a specification:

Figure l in the` drawing represents a central longitudinal vertical section; Fig. 2, a side view; Fig. 3, a transverse vertical section taken on the lineV X Y of my improved meter; Fig. 4 is a longitudinal view of the pisand Fig. 5 is a central longitudinal vertical section of the piston embodying the Same general principles as the above. i' The present invention relates to certain new and useful improvements in water or other meters, having for its main objects simplicity of construction" and operation, and economy in cost. My improvements consist in so arranging and operating a sliding valve, which is made a component part and horizontal half or other segmental portion of apiston, that stationary ports in a cylinder suitably connected with other ports in one-half of the piston, that water or other fluid, &c., entering through ports and channels connected therewith, cause one portion of a piston to slide longitudinally on theopposite or other portion of the piston, so as to change the `currentof water or steam, &c., from one end to the other of both, by which action thewhole piston is operated alternately from one end to the other of the cylinder.

a a in the drawing represent a cylinder provided on each side with ports b c and b c arranged alternately with and at a proper distance om each other, for the purpose hereinafter explained, and as shown in dotted lines of drawing, Fig. 2. Connecting with ,the cylinder a a is a vertical passage or inductionchamber, d, and an eduetion passage or chamber,d, each supplied with ports ef and e f', which connect by conduits g h and g h cast on the cylinder a a, and shown by the dotted lines, Fig.` 2, with the ports b c and b c. The

induction-chamber d is provided with an `induction-pipe, z', and the eduction-chamber d is furnished with an eduction-pipe, i. Traveling longitudinally within the cylinder a a is a piston of two horizontal parts or segments,

y k and l, either in half or other segmental pork. In the port m a stem, q, is tted so as to travel longitudinally in a slotted bar, o", connected with the induction-chamber d, for the purpose of preventing the rocking of the piston. The stem g only pertains to-this model, as I propose in a working-meter to set the port m longitudinally and insert a small vertical shaft down from the register, said shaft serving the purpose of steadying the piston, while at thesame time the longitudinal vibrations of the piston rotate the shaft, andl thereby the register.l The upper portion or segment k of the piston iinds a seat on a lower portion or segment, l, of the piston, which is provided with an @duction-port, s, that connects with the eduction-chamber el', and is separated by partitions w 'w' from two side vertical ports, t t', which connect with horizontal conduits, u and u', which extend longitudi- `nally to the end of the lower segment l, where they find an outlet into the cylinder a a. Nearr the ends of the segment l, extending transversely across it, and downward a sutcient distance to connect with the ports b c and b c', are formed Slots o and of, which, in connection with the segment k, form ports, two on each side, connecting with the cylinder-ports b c b c', and one at each end communicating with-` chambers z formed by the partitions :v as and the ends k k ofthe upper segmentk. These partitions w w may be differently arranged, as shown in Fig. 5. It will be observed that in Fig. l the partitions a," are permanent projections formed on the lower segment Z, and extending upward, and that the upper segment k isarranged with closed ends la lc extending downward and forming chambers z between them and the partitions :v w at either end, while in the modification, as shown in Fig. 5, the above arrangement is reversed and the partitions x x are formed on the upper segment la and extend downward, and the ends Z Z of the lower segment Z extend upward, So as to lill the main cylinder a a,

with the bridge waterY or other fluid, 8vo., passes from the induction-chamber d through the ports e b, t and conduit g on one side of the meter, and como municates with the exhausted chamber, (shown as closed in the drawing, Fig. 1but formed between the segments 7c and l by the partition m and end k of the upper segment k, and corresponding, when open, to the chamber 2,) which is thereby filled, and at the same time the water &c., in the full chamber z is exhausted through the ports fv c f and conduit h, thus causing the two segments k and l to slide longitudinally one upon the other, and in so doing change the current of the induction-water, Ste., to the opposite end of the whole pist0n in the main cylinder through the port t and conduits u connecting with the conduit n and port m, the water, Ste., during the passage of the piston, ndingan outlet through the port s into the eduction-chamber d', from which it escapes through the eduetion-pipe i. The above operation of the piston has caused the lower segment Z to open corresponding and channels or conduits g h' on the opposite side of the meter, these latter ports and channels bearing the same relation to and performing the same service of sliding the one segment on the other, and propeiling longitudinally, backward or forward, the whole piston, but in a contrary direction to that produced by the passage of the water, 8vo., through the ports and conduits rst referred t0.

Having thus described my improvements, what I claim as my invention, and desire to have secured to me by Letters Patent, is-

1. A Water or other meter having an outer cylinder, a a, in which travels longitudinally a piston composed of two horizontal halves or other segmentalportions k and l, arranged not merely as a valve slidin f on the piston within a cylinder, but constituting a component part of the piston, substantially as specied.

2. The cylinder a s, provided with induction-e a uber d and eduction-chamber df, connectin i ith induction-pipe and eduction-pipe i', and formed with ports e e', ff', Z1 c, and b c', and conduits g g', within which cylinder a o operates longitudinally the segments k and l of a traveling piston, substantially as described.

3. The horizontal piston, composed' of two horizontal halves or other segmental portions, k and l, the former of which is arranged with port m, conduit n nl, chambers z, and ,dome or D-valve p, operating on and in connection with the lower half or segment l formed with ports t t', port s, conduits u u', slots or ports 'v c', and partitions w m', so as to travel longitudinally one on the other, and within the cylinder a a, substantially as specified.

4. The partitions m formed either on the upper or lower segments 7c L, so as to form chambers z between themselves and the ends 7c la l l, either of the upper or lower segments 7c l, in combination with the slots or ports c e', ports b c b c', and cylinder a a, substantially as specified. y y y y y In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.
